Carbon Fiber 3D printer Filament?

[Yancy]

I don't think there is any carbon fiber filament that actually prints as strong as carbon fiber would be. Carbon fiber printing needs a totally different type of printer if you wish for the strength to be like that of real carbon fiber. The fibers need to be woven in such a way that normal extruders can not do.

Indeed.

Composite parts are made from sheets of interwoven strands. The fact that the strands are long and with different orientation provides the strength.

That's also why composite parts are so expensive : the plies are hand put (unless you're airbus or boeing) into molds to ensure correct fiber orientation.
